Asus P8Z77-V vs. Asus P8Z77-V-Pro

I have been looking up all the stuff and i am looking for more opinions

Differences

- The pro has 2 more USB 3.0 ports.
- The pro has Q-shield I/O anti-static back grill instead of normal
- The pro got 12 power phases instead of 8

- The pro has fan controller

If anyone knows of any other differences let me know. I am wondering
if people tend to just buy for the pro part or cause its actually worth it.
For me in particulair i am wondering if the fan controller validates the
16 euro,- aka 20 dollars extra.

also with the V pro you get an additional chassis fan header...which is sadly a large part of why i upgraded to that. HOWEVER microcenter was doing a combo i5 3570k for 190 if you buy the P8Z77 - V PRO for 170
